我厂在加工热交换器的管板零件的胀管槽(图1)时,过去是采用手动进刀的刀杆加工,不仅效率低,而且加工出来的槽深浅不一,同时也不够安全。后来,经过工人师傅们的研究,制成了自动进刀的钩刀(图2)。实践证明,这种钩刀,使用效果良好,不仅提高工效六倍多,而且保证了安全,提高了质量。 I plant processing heat exchanger tube plate parts of the expansion tank (Figure 1), the past is the use of manual feed arbor processing, not only inefficient, and the processed grooves of different shades, but also not safe enough. Later, after the study of the workers’ masters, a hook knife with automatic feed (Figure 2) was made. Practice has proved that this hook knife, the use of good results, not only to improve work efficiency more than six times, but also to ensure the safety and improve the quality.
